Title: Laser generator
IPC: H01S3/082
Filed: 1965-07-21
Abstract: 1,116,902. Lasers. CONTROL DATA CORPORATION. 21 July, 1965 [31, July, 1964], No. 31092/65. Heading H1C. In order to restrict laser oscillations to axial modes, one of a pair of oppositely disposed reflectors is as large as the diffraction pattern projected thereon by the second smaller reflector which is substantially smaller than its reflected diffraction on a plane located at the smaller reflector. In a helium-neon, R.F. pumped, gas laser. Fig. 1, the resonant cavity is formed by two external plane mirrors 21, 22, one of which, 22, is small compared to the other and to the diameter of the tube 12 containing the active medium 13. The laser output is taken from a Brewster angled window 14 in the end of the laser tubes nearest to the small reflector. The latter reflector is so small that its diffraction pattern illuminates an area many times greater than its own area so that the beam reflected from the large reflector diverges to substantially fill the tube adjacent the output window. A large proportion of the output from the window fails to strike the small reflector and the output is an axial mode. The small reflector may be mounted on the outside or inside of the Brewster window. In the arrangement of Fig. 2 (not shown), the small reflector is mounted on a convex lens and is itself convex which has a diameter slightly smaller than that of the laser medium, the lens also serving to focus or collimate the output beam. The large reflector may be concave or convex, Fig. 3 (not shown). Fig. 4 shows a Q switched laser in which a ruby crystal 51 has one face 52 ground to a concave surface and a large concave reflector 54 is positioned as shown so that in co-operation with the end 52 the output beam from end 53 is collimated. The small reflector comprises prism 55 and concave mirror 56, a Q-switch 57 being inserted in the reflected path. The laser medium may be solid, liquid or gaseous.

Abstract: 641,567. Automatic voltage control systems; smoothing direct currents. FURZEHILL LABORATORIES, Ltd., and SMITH & SONS (ENGLAND), Ltd., S. Nov. 28, 1947, No. 31583. [Classes 38 (ii) and 38 (iv)] In a D.C. voltage stabilizer of the type having an impedance in series with the output and a. variable impedance valve across the output, a second valve amplifies changes in current in the first and provides positive feed-back to accentuate the regulating action. A resistor 1, which may be constituted by the internal impedance of the supply, is connected in the positive line between input 12 and output 14; and a potential divider 2, 3, controls the bias applied to the grid of the regulating valve 4 connected across the output, variations in output voltage producing correcting variations in the impedance of the valve. A neon tube 5 provides a constant reference voltage in the cathode circuit, which also includes a resistor 6 which is common to a second valve 9, the grid of which is connected to the negative line, so that the voltage across resistor 6 is amplified and fed back by resistor'7 to the grid of valve 4 to augment any change in control voltage. Resistor 6 may be adjusted to give a minimum ripple voltage in the output. In a modification, Fig. 2 (not shown), the resistor 1 is replaced by an inductance, the neon tube 5 by a resistor, and the resistor 7 by a condenser, the circuit then serving to remove short period fluctuations only.
